METHOD OF AND MEANS FOR PRESERVING TENNIS BALLS OR THE LIKE Filed July 2, 1930 Patented May 23, 1933 PATENT [OFFICE WOODBRIDGE E. MORRIS, OF BALTIMORE, MARYLAND iun'rnon or AND MEANSFOR rnnsnnvine TENNIS BALLS on THELIKE Application filed J'ul y 2, 1930. serial No. 465,409.

This invention relates to themethod of and means for placing tennis or similar balls under compression whereby topreserve their resiliency or to maintain the lively quality of theballs. i 3

The primary object of the invention is the provision of acontainer in which one or more balls may be kept under compression. A further object of theinvention is the fn'ovision of a compression container of the kind described in which the balls are kept undercompression by mechanical means. A still further object of the invention is the provision of a compression containerin which pneumatic pressure may be maintained tothereby place the balls under compression. i a In order to disclose my invention I have illustrated and will presently describe a number of specific embodiments thereof,

but it will he understood that the accompanying illustrations and the following description are not exhaustive of the possible specific embodiments'whichmay be made in accordance with the teachings of this disclosure which, therefore, is to be considered as illustrative of the inventionand not as limited to the specific forms shown" and described, except as required th'edappended claims.

In thedrawingr Figure lis a. longitudinal sectionalview of lone form ofmy compression container; Figure 2 is, asection. on the line 2-2 of Figure 1; I t

Figure 3 1's asec'tional view of another form of compression container; i

Figure 4 is a sectional view of a container in which one 011111018b5t1lS are adapted to be maintained under pneumatic pressure;

Figure 5 is a sectional view of a modified form of pneumatic compression container. Referring to the drawing in detail, the compression container C shown in Figure 1 comprises two members or casing parts 10 and 11 hinged together at the edge1 12. Compartment forming members 13 and 14 are positioned within the casing parts 10 and 11. respectively. The compartment forming member 13 comprises a plurality thereto to afford tionsf21 and 22 which may be secured to the inside ofthe casing member 10, as by rivets, by spot welding, or in any other manner. lhe compartment tormmg member 14. has similar refiexe'd portions 23 and 24 secured to the casing section 11. Packing rings 25 are provided as shown for maintaining a fluid tight joint between the companion recessed members in the two compartment forming members 13 and 14...

A clamping device is provided for securing together the hinged casing sections 10 andlland for exerting. pressure on these members whereby to place under compreslsion the. balls within the cells or recesses: formed in the members 13 and 14. As here shown the clampingdevice isiormed by two lugs 26 and 27 secured to the sections 10 and 11, a screw threaded swivel pin 28having a ball joint 29in the lug 26, and aynut 30 longitudinally movable and rotatably .im-

movable within a recess-31 in the lug 27. The swivel pin 30 has a head 31 pivoted a convenient means for opcrating the clamping. device to exert the desired pressure on the balls within the casing.

; The construction shown in .Figure 3 is generally similar to that shown in Figures 1 and2. As shown in this figure the casing C includes two sections 10" and 11 hinged together at the edge 12 The compartment forming members 13 and 14 are formed integrally with the outer casing sections 10 and 11 respectively and are provided with

recesses

15 and 16" and an annular packing ring 25'. The casing and compartment forming sections may be formed in any. suit-p able manner as by casting operation. The

"casing sections may be clamped together by a spring hook device comprising a cylindrical member 82 pivotally secured to an ear 33 on the casing section 10 and a hook 341: which engages a ledge or projection 35 on the casin section 11, a spring 36 hearing on the hook to clamp together the casing sections 10 and 11. The compression container shown in this figure has one compartment or cell, but it will be understood that a plurality of compartments may be provided in this structure. It will also be understood that in the structure shown in Figure 1 the number of compartments may be increased or diminished.

Instead of placing the balls under compression by means of mechanical pressure provision may be made for compressing the balls by fluid, preferably, pneumatic pressure. 5 In Figures 4 and 5 of the drawing I have illustrated two specific embodiments of compression containers in which the balls may be kept under pneumatic pressure. The container shown in Figure 4 comprises a fluid tight casing G2 which includes a removable cover .37 which engages a gasket 38 forming a fluid-tight joint. The casing (.2 is provided with a check valve 39 which may be of any suitable construction, such as that of the ordinary tire valve, through which air under pressure may be supplied to the casing. The compression container shown in Figure 5 comprises a fluid tight casing C3 having a removable cover 40. This casing is provided with means for compressing the air therein. This air compressing means'comprises a piston 42 slidably mounted within the casing and provided with a peripheral packing (not shown) which engages the inner side wall of the.

casing. A screw-threaded rod 43 is connected to the piston 42 and engages a screwthreaded opening 44 in the cover 40 and is provided with a finger-piece 45 whereby the rod may be rotated to operate the piston whereby to compress the air within the casing.

The several pressure containers herein de scribed constitute a number of specific embodimeuts which are believed to adequately illustrate the invention, although certain changes in the construction and arrangement of parts might be made without departing from the fundamental inventive concept. It will also be understood that the compression containers may vary in size and shape to a considerable degree although I prefer that the container be of such size and shape as to be readily received within the ball compartment usually provided in the ordinary tennis racket cover. Thus, as shown in Figure 3 the casing C" can be constructed so that it is but slightly larger than the ordinary tennis ball. The intensity of compression pressure should be about equal to the internal pressure of the ball. IVhile I have the compartments may be such that the ball.

is received snugly therein without being compressed, the snug fit preventing expansion of the ball.

Having thus described my invention, what I claim is:

l. A ball compression container comprising a casing adapted to contain a ball, said casing comprisingtwo separable, hingedly secured parts, each part having a recess conforming to the curvature of the ball, said recesses forming together substantially spherical recesses slightly smaller than the ball, and means carried by the casing parts for holding said parts together against said ball whereby to exert pressure thereon.
